Abstract

Abstract Studies of the copolymerization of chloromethylstyrene (CMS) and divinylbenzene (DVB) were done in the presence or absence of poly-(vinyl chloride) (PVC) in order to prepare anion-exchange membranes of excellent performance by the paste method. The copolymerization rate decreases when PVC is added and increases when the DVB quantity is increased in the presence of PVC. The copolymerization rate of the isomers of CMS and DVB increases in the following order: p-DVB > m-DVB > p-ethylvinylbenzene > p-CMS > m-CMS ≈ m-ethylvinylbenzene. This order is not affected by the presence of PVC. The copolymerization of CMS and DVB takes place partially in PVC particles.
